What is login on Mac?

login · seed · quit hint: caution

login is a macOS process — also matched as com.apple.login. People usually find it in Activity Monitor when asking “what is this process?”

What does login do?

login authenticates a user (via PAM) and starts their login session, often as the parent of a shell or terminal session. Terminals, remote login services, and session tools invoke it. Quitting ends that login session and its child shell—do not kill active logins you still need.
